Analytical method of polycyclic aromatic hydrocarbons (PAHs) in oil contaminated soils

This study was performed to establish an analytical method of PAHs in oil contaminated soil of these methods by evaluating the PAHs test methods from US EPA and ISO etc. The application to domestic contaminated soil leads to a conclusion that alumina column is a more effective clean-up procedure for oil contaminated soil rather than the others. It is proposed with the new analytical method of 12 PAHs except for more volatile compounds (naphthalene, acenaphthylene, acenaphthene, fluorene). The recovery of PAHs in this method ranged 67~107%. The oil contaminated soil samples were analyzed using GC/MSD. The concentration of PAHs ranged 78.68~275.57 μg/kg. The predominated compounds were fluoranthene, pyrene and chrysene attributing about 70% of total concentration. The level of Benzo(a)pyrene ranged 1.76~24.65 μg/kg.
